Create two Series every Day and invite a resource with multipleBookings set 1.
One named "primary" from 10-11 which ends after 10 occurences.
Another named "second" from 11-12 which does not end.
Now pick a date after those 10 occurences of "primary" and change the time from 11-12 to 10:30-12. It should raise a conflict although "primary" has ended
preferrably it would be possible to change only future events (either by code or by implementing another menu-option "edit all future occurences") |
